Ahammed, Sajid

As a Doctoral Researcher and task leader in WP-1 within the Integrated Hydrogen-Argon Power Cycle (iHAPC) project at the University of Vaasa's Efficient Powertrain Solutions (EPS) research group, my work focuses on the optimization of advanced internal combustion engines for peaking power plant applications. Specifically, I lead the development of argon-based monoatomic gas mixtures, utilizing 1D simulations to fine-tune their thermophysical properties for system-level requirements. Building on my Master’s research in hydrogen-argon combustion systems in collaboration with Wärtsilä, I continue to refine hybrid hydrogen-based power cycles. My current work involves integrating a semi-predictive combustion model into the 1D engine simulation framework, in conjunction with 3D-CFD simulations, to enhance performance accuracy and optimize multi-parameter gas mixture designs. In addition to leading this research, I oversee the mitigation of knock and thermal stress issues through simulation-based analyses in GT-SUITE. I also coordinate the system-level design and simulations of the Argon Power Cycle (APC), ensuring alignment across various research work packages and facilitating the overall goals of the iHAPC project.
